corresponding parts throughout-the several views. .7 t Referring firstto Fig. 3, which illustrates my invention as practically applied tota wheel of a motor vehicle, the numeral 25 wheel whiohcont-ains a pneumatic tire26.

, bearing-connections, I have done-away with rimby means of the 'bolts24. The said inturned edges are, however,,carried farther and turned" toward the axle 9, to form a partial web on the inner fa'ceof the wheel,

to the wheel. This arrangement leaves the opposite faces of its rim open andunob-. cstructed,and also' strengthens the wheel by .stifienlng it. "a 4- tothe hollow hub 12 by threads and by the cap-nut 11,-.and' the hub has a cylindrical extension to the left hollowed out to receive Anti-friction balls 13 are seated between this cylindrical extension and said bearing, while other anti-friction balls 14: are seated be seen, that on account of the method'of support oft-he hub 12 by the outwardly dished web 23, the hub is so located as to lie'out-side'of the line which passes through ,t'he centers of the tires 26. This aflords space within the wheel for the reception of connections therein between the bearing 10 1 and 2. The upper surface of the bearing 10 may be flattened or provided with other seats for the upper half '18 of the leafspring shown, said spring being wholly located within the inner-space of the wheel and both halves thereof being orifieed in line to permit passage therethrough of the oppositely-directed vertical guide-bars 20 and 28 Similar numerals of! reference denote denotes the outwardlyeconcaved rim'of'the In order to securea central space. for the having a central axial opening 40 through which project the axle and other connections" 8, with-the wheel sectioned horizontally,

It will and the extremities of the frame cross-bars which have their inner ends connected to said bearing 10 and their-outer: ends supported by the brackets 19 and27'respectively, through whose bent-over ends 22 and 30 respectively their ends pass and are secured by the nuts 22 and 31. The guidebars are approximately vertical in the center line of the wheel-tread.

The extremity of theupper transverse frame-bar 1 is orificed to be. pivotally connected with the upper guide-bar 20 above the spring-half 18, while the similar orificed extremity of the lower frame-bar 2 is similarly pivoted on the lowermost guide-bar ,28 but rests upon the lower spring-half '29,

wheel .to change its direction of movement relative to the chassis 3. frame-bars 1 and 2 are connected by vertical braces 4 having medial bearings 5 for the axle-sections '6, the abutting ends of said sections 6 being connected.by'difierentialgearing 7. The outer end of each section 6 has a fiexible resilientconnection 8 with the inner end of the stub-axle 9, which permits the stub-axle to be shiftedin direction as desired by means'of its integral arm-15 with pivotal connection to a transverse rack-bar 17, pinions 34 and 38 meshing with said rack-bar to change its direction'of movement. Said pinions are supported in bearings in an arm 37 which is pivoted to the frame 3 and which permits up and down movements of the ends of the shafts 35 and 36 on which the pinions are mounted in the vertical spaces between the blocks 33. In Fig. 1 is shown an equivalent means for rendering the axle flexible and for shifting the stubaxles, which comprises the assemblage of intermediate axle-parts 55 with inner axle-parts 74 and with the stub-axles, the said parts being respectively flexibly connected by means of universal-joints 73 and .54 on each side. Inthe same way as above described, the stub-axles are actuated by means of arms 79 pivotally connected to transverse rack-bars 80, the latter being actuated by pinions 81 and 82 on shafts, 83 and 84 respectively, the axle-parts 74 being connected by differential gearing driven by the power-shaft 77 through the media of the pinions 76 and. 7 8. I

In Figs. 5 and 6 are illustrated a slightly variant form of my device as applied to the The transversewheel of a motor vehicle, in which twoi helical compression-springs 48 and 47 are used,-

instead of the leaf-springs above described.

In this case the spring 48, is coiled about the upper guide-bar 4'6 and rests upona plate 43 seated on the top of the bearing 10, while the spring 47 is seated about the lower guidebar 49 and rests upon the cross-bar ofIthe hangers 45.. The cross-barof the upper pair of supports 44 restrict thep'lay of the framebar 1 over the guide-bary 46 The lower:

frame-bar is'similarlypivotedto the guidebar 49 and rests upon thehelical lower spring 47. In this wheel, theyo'utwardlydished spokes 50 are used, which-laresecured means of plates 51 and rivets 52.. r

to'the rim 25 and fastened to the-hub 12 by- In Fig. 4 I show the same arrangementofparts as in Fig. 3, except that the wheelhas outwardly-dished spokes 50, whichv affords a central space for the" bearing-connections andexcept that the stub-axle is shown flexibly connected to'another axle-section 55 by means of a universal-joint 54, while an electrical motor 53 is mou'ntedupon the bearing of the stub-axle and adapted to drive the axle separately.

. In Fig. 7, I show my method displayed in i application to a car'wheel 56. a The wheel 56 x is cast with an interior hollow'with its outer face reinforced thickly at'57 for necessary strength, and its inner face having an axial opening 64 to "permit the reception'of the bearing 59 and its connections to the loadcarrying structure 62 and 61. The connec-' tions of said structure to 'tliefstub-axle' 58 are similar to that already described, the bearing '59 having vertical; oppositely-disposed guide-bars 20 and 28' for-the springhalves 18 and 29 and for the frame-exten- 810118 60 and '63, said extensions beingvsupported resiliently within the interior of. the wheel as alreadydescribed. The Figs, 8, 9

and 10 further illustrate this .idea as ex-.

emplified in use with a car-wheel 56. The detail is different in that a cross-axle 65 is used, and the truck-structure 67 and 69- has plates 66 and 68, above and below respectively which have pivotal connections with the guide-bars 20 and 28, the terminal nuts 70 and 71 ofthe latter retaining said'parts 66 and 68 on the'bars. In all these cases the application of the load is approximately in a line' running vertically through the tread of the wheel, and which thus lends strength tothe structure coupledwith ease of government. a

Having described my invention, what 1 claim as new, and desire to secure by Letters Patent, isz.

spindle, oppositely-directed vertical guidebars fixed to said bearing, connected springs located respectively above and below said 1 Incombination, a wheel secured on a I rotary splndle, a sleeve-bearing about said bearing, the one resting upon the bearing, and the other movable over the under guidebar, and rigidly connected frame-members, one movable over the upper guide-bar over the upper spring, and the other supported on their upper and lower ends respectively,

springs located respectively above and below said bearing, the one resting upon the hearing, and the other mounted on the lower guide-bar, and rigidly-connected framemembers, one slidably mounted upon the upper guide-bar between the stop on the latter and the uppermost spring, and the other supported'on the lower spring and slidably mounted on the lower guide-bar between said spring and said bearing.

3. In combination, a wheel secured on a rotary spindle, a sleeve-bearingabout said spindle, oppositely directed vertical plates fixed to said bearing and having their extremities bent over at 'a right angle, oppositely-directed vertical guide-bars fixed to said bearing adjacent and parallel to said plates and having their extremities detachably secured to the bent-over parts. of the latter, connected springs located respectively above and below said bearing, the one resting upon the bearing and orificed to be mountedupon the upper guide-bar, the

other being orificed to be slidably mounted upon the lower guidebar, rigidly-connected frame-bars, the .end of one being orificed to be slidably mounted upon the upper guidebar above the upper spring and the other having its end orificed to be slidably mounted upon the lower guide-bar and supported upon the lower spring.
